High - Efficiency NBGE End - Suction Power Supply for Demanding Applications The Grundfos NBGE end - suction close - coupled pump is a non - self - priming single - stage centrifugal volute pump with an axial suction port, a radial discharge port, and a horizontal shaft. If your pump is for demanding applications with different flow requirements, the NBGE can be equipped with an 11 - kW permanent - magnet MGE motor, with a built - in variable - frequency drive and IE5 efficiency, maintaining high efficiency at all times. The close - coupled pump has a compact design and can be installed in limited areas. The main dimensions of the NBGE pump comply with the ISO 2858 standard. All Grundfos end - suction pumps are tested according to the acceptance grade standard of ISO 9906:2012 before leaving the factory. |

NBGE 125 - 80 - 160/161 AAF2AESBAQEPWB The non - self - priming single - stage volute centrifugal pump is designed in accordance with the ISO 5199 standard, and its dimensions and rated performance comply with the ISO 2858 standard (16 bar). The flanges are of PN 16 type, and their dimensions conform to the EN 1092 - 2 standard. The pump is equipped with an axial suction port, a radial discharge port, a horizontal shaft, and a back - pull - out design, which allows maintenance personnel to disassemble the motor, motor base, cover, and impeller without loosening the pump casing or pipes. The unbalanced O - ring shaft seal meets the DIN EN 12756 standard. An air - cooled permanent - magnet synchronous motor is closely coupled to the pump. The junction box of the motor contains a frequency converter and a PI controller. This enables the system to continuously adjust the motor speed, allowing the pump to be adjusted to the optimal working state according to the environmental conditions. | ![]() |
